Does TFP-410 chip support interlace video input?

Hi I.K.,

We already make an experiment, we use TI J6 dra74x vout-2 port to output RGB24 with 1280x800@60 progressive video signal as TFP-410 input, then use HDMI monitor to see the TFP-410 output, i can see the pattern we send.
But if i send the same pattern(only modify vout-2 as interlace mode and pixel clock is half of original one), then i can't see anything on monitor.
May i say the TFP-410 doesn't support interlace video input?

Hi Shawn,

What frequency was the original pixel clock, and are you using this device in 1-pixel/clock mode or 2-pixel/clock mode?

Hi I.K.

The original pixel clock for RGB24 1280x800@60 is 70MHz.

Where can i find out this setting?

Hi Shawn,

My mistake, I was looking at the TFP401 datasheet rather than the TFP410, thinking maybe you could try switching between 1-pixel/clock mode and 2-pixel/clock mode. However, the TFP410 only has 1-pixel/clock mode so that wouldn't be the issue here.
